摘要

太赫兹波的衰减性及高可用带宽使其在局域网环境中拥有广阔的应用前景. 而太赫兹波的窄波束问题需要借助波束成形技术来解决. 作为波束成形技术的关键内容，非直视情况下太赫兹频段的室内信道建模成为了当前亟待开展的工作. 本文在340 GHz频段对多种常见室内装饰材料的太赫兹波反射特性和室内多径反射信道特性进行了实验研究，并基于射线追踪法对太赫兹室内信道进行仿真，仿真结果与测量结果符合较好，为进一步太赫兹室内信道建模提供了基础.

Abstract

Ultra-broadband terahertz communication systems are expected to help satisfy the ever-growing need for unoccupied bandwidth. Due to high attenuation of terahertz wave, it can be widely used in indoor WLAN data communication. Future THz WLANs will rely on not only the line-of-sight (LOS) but also the nonline-of-sight (NLOS) channels to perform data communication. Hence, both kinds of channels have to be characterized. In this paper, we present the measures of ultra-broadband channel at 340 GHz for an indoor scenario. The measured channel transfer function is compared with a ray tracing simulation performed with the indoor scenario. Additionally, we show the reflection losses of some building and plastic materials which could be required as input data for the ray tracing algorithm.
